7850 Extension Switch Hardware Installation Guide
If your device is up and running with six fan assemblies, but one or more of them has failed, perform the following steps:
1. Remove the old or failed fan assembly.
2. Insert the new fan assembly.
3. Verify the fan assembly status LED.
Inserting a New Fan Assembly
Complete the following steps to insert a new fan assembly into the chassis.
The new fan assembly must have the same part number and airflow label (or lack thereof) as the fan assemblies already
installed.
1. To leave the device in service while installing a fan assembly, verify that the other fan assemblies (the ones already
installed) have been powered on for at least 4 seconds and have a steady green LED.
2. Using a Phillips screwdriver, unscrew the captive screw of the fan assembly and remove the fan assembly.
3. Orient the new fan assembly with the captive screw on the right, as shown in the following figure.
Do not force the installation. If the fan assembly does not slide in easily, ensure that it is correctly oriented before
continuing.
CAUTION
Carefully follow the mechanical guides on each side of the fan assembly slot and make sure that the fan
assembly is properly inserted in the guides. Never insert the fan assembly upside down.
